"As Michigan State University moves to reduce energy consumption and transition to more renewable sources, it is clear that the university's hundreds of buildings must operate more efficiently," said Ann Erhardt, director of MSU Sustainability. "To do this, MSU is leading the way with several significant energy-conservation initiatives. These will build the foundation needed to make the transition to renewable energy sources and meet campus energy-conservation goals."

More than 150 countries representing around 90% of all global emissions have offered climate pledges. These actions are a great step forward in highlighting American leadership on climate action and ensuring a successful global agreement on climate change.
